FAN.

Specification of Letters Patent.

Patented Aug'. 20, 1907.

Application flied April 1, i907. serai No. 365,816.

To all whom it may concern:

Be it known that I, OTTO SELG, a citizen of the United States, residing at New vYork city, (Manhattan,) county and State of New York, have invented new and useful Improvements in Fans, of which the following is a specification.

This invention relates to a fan designed to produce a superior distribution of the air current by spreading the same in various diverging directions over an increased area In the accompanying drawing: Figure 1 is a side elevation of my improved fan; Fig. 2 a detail of part of the deflect'or; Fig. 3 a detail of a further part of the deflector; Figf4'a detail of a modification of part of the de# Hturns in a housing 12, and is preferably drive by elec-` tricity in the usual manner. In front of the fan there is secured to housing 12, by a frame 13; a defiector designed to effect a radial dissemination of the air blast. This defiector is composed of a nest of concentric coned rings 14 which are so arranged that the inner edge of any one ring is overlapped by the outer edge of the surrounding ring. In this Way the rings are set in advance of one another from the center towards the periphery of the deflector and form jointly a coniform outline. Between the rings are formed angular air spaces, which by the construction described, cause a thorough diffusion of the air passing through said spaces. The rings gradually decrease in diameter from the outermost ring towards the inner ring, and each ring is so mounted that it flares outwardly from the source of .the air blast. Frame 13 is composed of a series of arms that converge towards the front of the fan, and form an open-work coniform support for the rings. The latter are mounted upon the. arms back of each other, and at such distances apart as to obtain the overlapping effect desired. ln order to secure the rings to the arms, the latter are provided with grooved lugs 22 which are spaced to correspond to the spacing desired for lthe rings and which grasp the rear edges of said ring To further divert or break up the currents of air flowing between the rings, thc latter are so corrugated radially as to form alternate inwardly deflected sections 15, 1G, of varying depths` Some or all of these sections may be perforated, the drawing showing the innermost ring to be so perforated as at 17. In lieu of corrugating the rings, the deiiected sections may be produced by radial incisions extending partly through the same to form the sections 18, 19, which are turned inwardly at different angles, (Fig. 4). In Fig. 5, the inwardly turned sections are dispensed with andthe ring 20 provided with a serrated outer edge 2l, which eHects the desired breaking up of the air.

It will be seen that by my invention the current of air is so distributed that a uniform cooling effect, over an increased area, is obtained.

`I claim:

l. A fan provided with a housing, a series of converging' arms secured thereto, and a series of coiled rings mounted hack of each other upon said arms, substantially as specified. v

A fan provided with a housing, a series of converging arms secured thereto and having spaced lugs, and a series of coned rings mounted back of each other upon said arms and engaging said lugs, substantially as specified.
